In a 2-year study, fruit from eight redand eight yellow-skinned ‘White Angel’× ‘Rome Beauty’ hybrid selections were stored for 21 weeks at 0.5°C plus 1 week at 20°C and evaluated for the incidence and severity of superficial scald. Five red-skinned (R-03, R-20, R-22, R-48 and R-85) and three yellow-skinned (Y-26, Y-55 and Y-65) selections were examined in both seasons. Peel-tissue samples taken...

In ecology much attention has been paid towards seed dispersal of fleshy-fruited plants, however, knowledge is lacking about the long-term demographic consequences of variation in dispersal distance and fruit removal rate, particularly given the natural variability of the environment the organism lives in. In this study we used a spatially explicit, two-level stochastic computer model to simula...

The effects of selection on genome variation were investigated and visualized in tomato using a high-density single nucleotide polymorphism (SNP) array. 7,720 SNPs were genotyped on a collection of 426 tomato accessions (410 inbreds and 16 hybrids) and over 97% of the markers were polymorphic in the entire collection. Principal component analysis (PCA) and pairwise estimates of F(st) supported ...

Varieties of red currant various genetic as well ecological and geographical origin from breeding schools in Russia, Belarus, Great Britain, Germany, Latvia, the Netherlands, Slovakia, Ukraine were studied conditions found Belarus. with a long raceme largest number berries that are Blanca, Dana, Nenaglyadnaya, large-fruited varieties Jonker van Tets, Rondom have been determined. characterized b...

BACKGROUND AND AIMS The taxonomic complexity of Crataegus (hawthorn; Rosaceae, Maleae), especially in North America, has been attributed by some to hybridization in combination with gametophytic apomixis and polyploidization, whereas others have considered the roles of hybridization and apomixis to be minimal. Study of the chemical composition and therapeutic value of hawthorn extracts requires...

We studied the influence of branch autonomy on the growth of reproductive and vegetative organs by establishing different patterns of fruit distribution within and between large branch units (scaffolds) in mature peach trees (Prunus persica (L.) Batsch cv. 'Elegant Lady'). Different patterns of fruit distribution were established by defruiting either whole scaffolds (uneven fruit distribution b...

BACKGROUND AND AIMS In arid environments many plant species are found associated with the canopies of woody perennials. Favourable conditions for establishment under canopies are likely to be associated with shade, but under canopies shade is distributed patchily and differs in quality. Diurnal temperature fluctuations and maximum temperatures could be reliable indicators of safe sites. Here, a...

Land abandonment is one of the most powerful global change drivers in developed countries where recent rural exodus has been the norm. Abandonment of traditional land use practices has permitted the colonization of these areas by shrub and tree species. For fleshy fruited species the colonization of new areas is determined by the dispersal assemblage composition and abundance. In this study we ...

Bell pepper (Capsicum annuum L.) grown in Florida has traditionally been field-grown and harvested at a mature-green stage. However, the demand for highquality colored pepper has led producers to look at pepper grown under protected structures. Thirty-six colored pepper cultivars (red, orange, yellow, chocolate, and purple) from both Israeli and Dutch seed companies were compared during the Fal...
